Introduction
A three-month period in 2005, two distinct types of methicillin-sensitive Staphylococcus aureus (one producing of Panton-Valentine leukocidin (PVL) and the other not) were isolated from bronchial specimens of paediatric inpatient unit at the Zou/Collines Departmental Hospital (CHDZ/C), who had been previously cared for by the nurses. The source of outbreak was probably a faulty contamination of specific food consumed by patients.
